Multi-Channel Radio Transmitter Dynamic Channel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless control systems for environment protection devices, such as roller shutters and sunshades, face inefficiencies due to the need for multiple identical radio transmitters, leading to uncertainty in channel selection and unnecessary complexity when the number of devices exceeds the fixed number of channels in multi-channel transmitters.
Innovation Solution
A multi-channel transmitter system that dynamically adjusts the number of active channels based on the number of environment protection devices, utilizing a microprocessor-controlled learning program to enable only necessary channels, simplifying user operation and adapting to system changes.

Engineering Contradiction Analysis
1Ease of operation
If multiple identical radio transmitters are used to control each environment protection device, then wireless control capability is achieved, but channel selection uncertainty and system complexity increase
Solution Approach 1:
Multiple identical transmitters are merged into a single multi-channel transmitter that can control multiple environment protection devices. The transmitter incorporates multiple radio channels (e.g., 8 channels) within one device, eliminating the need for multiple separate transmitters and simplifying channel selection for the user.
Solution Approach 2:
The radio transmitter is designed with multi-functionality to control different types of environment protection devices (roller shutters, sunshades, skylights) through multiple channels. Each channel can be independently tuned to a specific device, making the single transmitter universal for controlling multiple devices with different functions.
2Adaptability or versatility
If a fixed number of channels is provided in multi-channel transmitters, then device integration is achieved, but channel mismatch occurs when the number of devices differs from the number of channels
Solution Approach 1:
The transmitter channel configuration is made dynamic through a learning program that automatically adapts the number of active channels to match the actual number of environment protection devices in the system. The system can dynamically enable or disable channels based on device presence, eliminating fixed channel limitations and simplifying operation by preventing channel mismatch errors.
3Stability of the object's composition
If unused channels are included in the transmitter, then fixed channel structure is maintained, but user operation becomes complicated due to searching through unnecessary channels
Solution Approach 1:
Unused or unnecessary radio channels are extracted or removed from the active transmitter configuration through the learning program. The system identifies which channels correspond to actual devices and disables unused channels, maintaining the stable multi-channel structure while eliminating operational complexity by preventing users from searching through inactive channels.
